Human cytochromes P450 2S1 and 2W1 have received only limited attention with regard to characterization of function. Both cytochromes P450 have been reported to be overexpressed in human tumors, and cytochrome P450 2S1 is induced by carcinogenic polycyclic hydrocarbons. We report methods for high-level expression and purification of both cytochromes P450 from Escherichia coli, with the goal of ...

Numerous cytochrome P450 inhibitors have been described as effective modulators of cytochrome P450 isoforms activity in vitro. Their inhibitory efficiency may be considerably modified after in vivo application. The aim of this study was to examine the effect of oral administration of diallyl sulfide--a cytochrome P450 2E1 inhibitor and cimetidine--a cytochrome P450 2C6 and 2C11 inhibitor on rat...

Twenty five derivatives of the drugs terfenadine and ebastine have been designed, synthesized and evaluated as inhibitors of recombinant human CYP2J2. Compound 14, which has an imidazole substituent, is a good non-competitive inhibitor of CYP2J2 (IC(50)=400nM). It is not selective towards CYP2J2 as it also efficiently inhibits the other main vascular CYPs, such as CYP2B6, 2C8, 2C9 and 3A4; howe...

Cytochrome P450 enzymes (P450s, CYPs) are a superfamily of heme–thiolate proteins involved in the metabolism endogenous and exogenous substances insects. In this study, identification putative was done elimination repeated sequences resulted 57 from Gastropacha populifolia , 63 Dendrolimus punctatus 53 tabulaeformis . The were aligned together with seven other insect species based on five conse...
